Perspectives on Safety

Our Perspectives on Safety section features expert viewpoints on current themes in patient safety, including interviews and written essays published monthly. Annual Perspectives highlight vital and emerging patient safety topics.

Interview

Pat Croskerry, MD, PhD, is a professor in emergency medicine at Dalhousie University in Halifax, Nova Scotia, Canada. Trained as an experimental psychologist, Dr. Croskerry went on to become an emergency medicine physician, and found himself surprised by the relatively scant amount of attention given to cognitive errors. He has gone on to become one of the world's foremost experts in safety in emergency medicine and in diagnostic errors. We spoke to him about both.

Perspective

Emergency medicine has evolved from a location, with variably trained and experienced providers ("the ER"), to a discipline with a well-defined knowledge base and skill set that focus on the diagnosis and care of undifferentiated acute problems.(1) The importance of rapid diagnosis and treatment of serious conditions (e.g., myocardial infarction, stroke, trauma, and sepsis) has made timeliness not simply a determinant of patient satisfaction but also a significant safety and quality concern—delays in care can be deadly.(2) Emergency physicians (EPs) have identified delays caused by crowding from boarding of admitted patients as their most significant safety problem.(3) We present a model for understanding emergency department (ED) patient safety and identify solutions by deconstructing care into three realms: individual provider, patient, and environmental system (Table).
